I side with Dennett (and Turing for that matter) that a "p-zombie" is a logically incoherent thing. Demonstrating understanding is the same as having understanding because there is no test that can distinguish the two.
Are LLMs human? No. Can they do everything humans do? No. But they can do a large enough subset of things that until now nothing but a human could do that we have no choice but to call it "thinking". As Hofstadter says - if a system is isomorphic to another one, then its symbols have "meaning", and this is indeed the definition of "meaning".
